Frequently Asked Questions
-
L-theanine produces measurable alpha brain wave increases within 30-40 minutes of ingestion. Most people notice a sense of calm focus within 30-60 minutes. Unlike prescription anti-anxiety medications, it works quickly without sedation, cognitive impairment, or dependence.
-
Yes — this is the most well-studied nootropic combination. L-theanine (200mg) smooths caffeine's stimulatory effects, reducing jitteriness and anxiety while preserving alertness and focus. Studies show the combination improves attention and task-switching better than either alone. The ideal ratio is 2:1 theanine to caffeine.
-
Yes. L-theanine is one of the safest supplements available — it's the primary amino acid in green tea. Doses up to 400mg/day have shown no adverse effects in clinical studies. No tolerance builds up, no withdrawal, and no dependence. It can be taken daily for years without concern.
-
L-theanine improves sleep QUALITY without causing drowsiness — it promotes relaxation and reduces racing thoughts, making it easier to fall asleep. It's particularly effective for people whose insomnia is driven by anxiety or an overactive mind. Take 200-400mg about 1 hour before bed. Unlike melatonin, it won't make you groggy if you need to wake up.
